Abstract
Large-area icing is a natural disaster that presents a serious threat to the safety of aerospace and power systems, so achieving fast and efficient de-icing is an important cornerstone of energy security. In this paper, a physical model of the field-circuit coupling of the pulsed coil is established. The transient process of the pulsed coil was solved by numerical calculation method, and the magnetic induction intensity distribution, pulse current, impulse force and pulse effect under different cases were obtained. The electromagnetic parameters and pulse effect of the pulsed coil under different structural parameters are compared, and the influence of structural parameters on the pulse effect is analyzed. The results show that the pulse effect can be improved by adopting a reasonable cross-sectional form, increasing the cross-sectional area, decreasing the inter-turn distance and increasing the number of turns and outer diameter. Finally, the electromagnetic parameters and pulse effect of the pulsed coil are verified by impact pendulum experiments, which prove the correctness of the model. The conclusions of this work can provide analytical paths and optimization ideas for the de-icing simulation and low-power design of electromagnetic impulse de-icing systems.
